My guess is that a native iPad app is relatively low priority. The standard web app, app.rach.io, works quite well on the iPad and I suspect that’s what most iPad users are using. I mostly use the web app for serious configuring and only use the iPhone app when I’m wanting to do manual runs out on my property in areas where I have cell coverage (not a lot, I’m afraid). The few times I’ve wanted to use an iPad, the web app did all I needed.

A native iPad app is a request that is in our backlog, but it is fairly low priority. Like @shcaine mentioned, our web app is designed to work well on mobile phones and tablets, and I think this is the best option when using the iPad!
